If you think you might have fibromyalgia, see your doctor for a diagnosis. When you visit your doctor, your doctor will do a physical examination and ask you some questions about your medical history and symptoms. Your doctor may apply mild pressure to different areas of your body to check for tenderness.

Because the symptoms of fibromyalgia may overlap with many other conditions, your doctor may do additional tests to rule out other possible causes. Common tests your doctor may order include a complete blood count, erythrocyte sedimentation rate (ESR; a test that looks for inflammation in the body), or thyroid function tests.

If you are diagnosed with fibromyalgia, your doctor may refer you to a rheumatologist. A rheumatologist is a doctor who specializes in conditions that affect the joints and soft tissues, such as arthritis and fibromyalgia.

To help you prepare for your doctor's visit, see "Talking to your doctor about fibromyalgia."
